Scotland in the High Middle Ages in the context of "History of Scotland"

Scottish people or Scots (Scots: Scots fowk; Scottish Gaelic: Albannaich) are an ethnic group and nation native to Scotland. Historically, they emerged in the early Middle Ages from an amalgamation of two Celtic peoples, the Picts and Gaels, who founded the Kingdom of Scotland (or Alba) in the 9th century. In the following two centuries, Celtic-speaking Cumbrians of Strathclyde and Germanic-speaking Angles of Northumbria became part of Scotland. In the High Middle Ages, during the 12th-century Davidian Revolution, small numbers of Norman nobles migrated to the Lowlands. In the 13th century, the Norse-Gaels of the Western Isles became part of Scotland, followed by the Norse of the Northern Isles in the 15th century.

In modern usage, "Scottish people" or "Scots" refers to anyone whose linguistic, cultural, family ancestral or genetic origins are from Scotland. The Latin word Scoti originally referred to the Gaels, but came to describe all inhabitants of Scotland. Considered pejorative by some, the term Scotch has also been used for Scottish people, now primarily outwith Scotland.

Edmund I or Eadmund I (920/921 – 26 May 946) was King of the English from 27 October 939 until his death in 946. He was the elder son of King Edward the Elder and his third wife, Queen Eadgifu, and a grandson of King Alfred the Great. After Edward died in 924, he was succeeded by his eldest son, Edmund's half-brother Æthelstan. Edmund was crowned after Æthelstan died childless in 939. He had two sons, Eadwig and Edgar, by his first wife Ælfgifu, and none by his second wife Æthelflæd. His sons were young children when he was killed in a brawl with an outlaw at Pucklechurch in Gloucestershire, and he was succeeded by his younger brother Eadred, who died in 955 and was followed by Edmund's sons in succession.

Æthelstan had succeeded as the king of England south of the Humber and he became the first king of all England when he conquered Viking-ruled York in 927, but after his death Anlaf Guthfrithson was accepted as King of York and extended Viking rule to the Five Boroughs of north-east Mercia. Edmund was initially forced to accept the reverse, the first major setback for the West Saxon dynasty since Alfred's reign, but he was able to recover his position following Anlaf's death in 941. In 942, Edmund took back control of the Five Boroughs and in 944 he regained control over the whole of England when he expelled the Viking kings of York. Eadred had to deal with further revolts when he became king, and York was not finally conquered until 954. Æthelstan had achieved a dominant position over other British kings and Edmund maintained this, perhaps apart from Scotland. The north Welsh king Idwal Foel may have allied with the Vikings as he was killed by the English in 942. The British kingdom of Strathclyde may also have sided with the Vikings as Edmund ravaged it in 945 and then ceded it to Malcolm I of Scotland. Edmund also continued his brother's friendly relations with Continental rulers, several of whom were married to his half-sisters.

The Gallowglass (also spelled galloglass, gallowglas or galloglas; from Irish: gallóglaigh meaning "foreign warriors") were a class of elite mercenary warriors who were principally members of the Norse-Gaelic clans of Ireland and Scotland between the mid 13th century and late 16th century. It originally applied to Highland Scots, who shared a common background and language with the Irish, but as they were descendants of 10th-century Norse settlers who had intermarried with the local population in western Scotland, the Irish called them Gall Gaeil ("foreign Gaels").

An early family of gallowglasses was the MacSweeneys, settled by the O'Donnells in north Donegal. These were followed by MacDonnells, MacAlisters, MacCabes and several other groups settled by powerful Irish nobles in different areas. The gallowglasses were attractive as heavily armoured, trained infantry to be relied upon as a strong defence for holding a position, unlike most Irish foot soldiers, who were less well armoured than the typical Irish noble who fought as cavalry.

The Justiciar of Scotia (in Norman-Latin, Justiciarus Scotie) was the most senior legal office in the High Medieval Kingdom of Scotland. Scotia (meaning Scotland) in this context refers to Scotland to the north of the River Forth and River Clyde. The other Justiciar positions were the Justiciar of Lothian and the Justiciar of Galloway.

The institution has some Anglo-Norman origins, but in Scotland north of the Forth it represented some form of continuity with an older office, a senior version of a Judex or Brithem, a native Scottish lawman often with province-wide responsibilities. Mormaer Causantín of Fife was styled judex magnus (i.e. "great Brehon") in Scotia, and it is probable that the Justiciarship of Scotia was just a further Latinisation/Normanisation of that position. By the middle of the thirteenth century, the responsibilities of the Justiciar became fully formalised. He supervised the activity and behaviour of royal sheriffs and sergeants, held courts and reported on these things to the king personally.
